Description

  The present invention relates to a workbench that is used in a manual sorting operation for industrial waste or the like.

  To recycle industrial waste (waste plastics, paper waste, wood waste, metal waste, rubble, waste gypsum board, glass ceramic waste, etc.) discharged from factories, etc. Sorting work (so-called intermediate processing) is widely performed. In separation work, industrial waste brought from industrial factories to industrial waste disposal companies is first subjected to rough separation using heavy machinery, etc. (metal materials mixed in industrial waste using a magnetic separator) In the end, sorting of industrial waste is performed as much as possible according to the purpose of recycling, etc. by manual sorting (sorting by hand).

  And about the industrial waste sorted by the intermediate processing company, appropriate processing, such as recycling and a landfill, is performed respectively according to a recycling use. In other words, the industrial waste separated by the intermediate treatment contractor is processed by each process contractor for each finally sorted item (waste plastics, paper waste, wood waste, metal waste, rubble, waste gypsum board, glass ceramic waste, etc.). To be recycled, recycled or disposed of in landfills.

  When an operator separates industrial waste as described above, a manual separation conveyor device as disclosed in Patent Document 1 is used. The manual separation conveyor device of Patent Document 1 (a conveying device in which an infinite circulation zone such as a belt or a chain is installed on a pulley or gear driven by an external driving force such as an electric motor: linear type) is used for a plurality of manual separations. Efficient use of space at the work site for manual separation (sorting by human hands) due to the property that it can be arranged in series in a waste disposal space without any effort from the state in which conveyor devices are stacked. Is to be able to.

JP 2010-47404 A

  However, in the conveyor device for manual separation according to Patent Document 1, waste plastics, paper waste, wood waste, metal waste, rubble, waste gypsum board, glass ceramic waste, etc. are mixed on a conventional (linear) conveyor. Industrial waste (hereinafter referred to as mixed waste) is still flowing from right to left.

  With such a structure, when the mixed waste flowing from the upstream to the downstream of the linear conveyor device flows in large quantities and exceeds the processing capacity, it cannot be processed when the separation work cannot catch up. The mixed waste flows to the next process. Therefore, you cannot leave the place at all during work. When all the workers have to leave the place (in the case of emergency, toilet, etc.), the work must be stopped by temporarily stopping the conveyor. Even if only a few people were in charge, it was necessary to adjust the separation line speed when one or two people had to leave the place. It is not preferable to temporarily stop the supply because it is necessary to adjust the supply amount.

  The purpose of the present invention is to fundamentally review the form of the conventional linear conveyor device and make it a circular or donut disk-shaped turntable, so that the sorting work can catch up with the manual sorting work of industrial waste etc. An object of the present invention is to provide a rotary industrial waste sorting work table in which the mixed waste that has not returned returns to the worker as many times as possible so that the sorting work is not missed.

  In order to solve the above-mentioned problem, the invention described in claim 1 is a separation work table used in the separation work of industrial waste, etc., and is a disk-shaped or donut disk-shaped turntable, and its rotation And a base that rotatably supports the base, and the base rotates around a horizontal axis extending in the radial direction from the center of rotation of the rotary base in a state of contact with the back surface of the rotary base. A plurality of vertical rotating wheels, and a plurality of horizontal rotating wheels that rotate around a vertical axis in contact with the peripheral edge (outer peripheral edge or inner peripheral edge) of the rotating table. It is.

  The invention described in claim 2 is the invention described in claim 1, wherein an inner edge side ring having a constant width is formed on the rear surface of the turntable in a circumferential shape concentric with the center axis of the turntable, and It is provided so as to be orthogonal to the back surface of the turntable, and at least a part of the plurality of vertical rotating wheels is provided circumferentially so as to be adjacent to the inner side of the inner edge side ring. It is what.

  The invention described in claim 3 is the invention described in claim 1 or 2, wherein an outer edge side ring having a constant width is provided on the rear surface of the turntable and outside the inner edge side ring. Is provided so as to be concentric with the central axis of the rotating table and perpendicular to the back surface of the turntable, and at least a part of the plurality of vertical rotating wheels is adjacent to the outer side of the outer edge side ring. Thus, it is provided in the shape of a circle.

  The invention described in claim 4 is the invention described in any one of claims 1 to 3, wherein the plurality of horizontal rotating wheels are an outer peripheral surface or an inner peripheral surface of the inner edge side ring or the outer edge side ring. It is characterized by rotating around a vertical axis in contact.

  The invention described in claim 5 is the invention described in any one of claims 1 to 4, characterized in that at least a part of the vertical rotating wheel is rotated by an external driving force. To do.

  The greatest feature of the rotary industrial waste sorting worktable according to claim 1 is that the shape seen from directly above is a disk shape or a donut disk shape. Since the mixed waste moves while rotating on a disk-shaped or donut disk-shaped turntable, mixed waste can be returned to the same location as many times as long as the worker does not perform sorting work. become. In other words, when the mixed waste flows for the first time, even if the separation work cannot be performed for some reason, the separation work should be performed when the mixed waste flows again. The situation of failing to occur does not occur.

  The rotary industrial waste separation workbench according to claim 2 is provided in a circular shape so that a vertical rotary wheel is adjacent to an inner ring on the back surface of the rotary table. Therefore, even if the turntable receives external force in the horizontal plane direction, if the position of the rotation center of the turntable shifts, the inner edge side ring will hit the vertical rotating wheel. The amount is kept within a certain range. That is, the rotary industrial waste sorting platform according to claim 2 functions as a guide for preventing the vertical rotation wheel inside the inner ring on the inner edge side ring from shifting the position of the rotation center of the turntable. The amount of displacement can be suppressed within a certain range.

  The rotary industrial waste separation workbench according to claim 3 is provided in a circular shape so that vertical rotating wheels are adjacent to the outer side of the outer ring on the back surface of the rotary table. Therefore, even when the turntable receives external force in the horizontal plane direction, if the position of the rotation center of the turntable shifts, the outer ring will come into contact with the vertical rotation wheel. The amount is kept within a certain range. That is, the rotary industrial waste sorting worktable according to claim 3 functions as a second guide for preventing the vertical rotation wheel on the outer side of the outer ring on the outer edge side ring from being displaced at the rotation center of the turntable. The amount of displacement of the turntable can be suppressed within a certain range.

  The rotary industrial waste sorting platform according to claim 4 includes a horizontal rotating wheel that rotates in a state in contact with the outer peripheral edge or the inner peripheral edge of the inner edge side ring or the outer edge side ring. Can be prevented more accurately, and even if the turntable is lightweight, it can be smoothly rotated (without causing the vertical rotating wheels including the drive wheels to idle).

  The rotary industrial waste separation workbench according to claim 5 is configured to rotate the turntable freely and automatically at an arbitrary timing by rotating some of the plurality of vertical rotating wheels by the action of an external driving force. Can be made.

It is a perspective view of the rotary industrial waste sorting worktable concerning this example. It is the plane schematic diagram and the cross-sectional schematic diagram for demonstrating the structure of a rotary industrial waste separation worktable. It is explanatory drawing which shows the installation state of a vertical rotation wheel and a horizontal rotation wheel.

<Structure of rotary industrial waste sorting platform>
Hereinafter, an embodiment of a rotary industrial waste sorting table (hereinafter simply referred to as a sorting table) according to the present invention will be described in detail with reference to FIGS. 1 and 2 show a sorting work table according to the present invention, and the sorting work table 1 has a rotating table 4 whose overall shape viewed from right is a donut disk shape (see FIG. 1). 1, see FIG. 2 (a)), while continuously receiving the mixed waste to be carried to be separated, the mixed waste is moved by rotating the turntable 4 (rotates on the turntable 4). This is a rotary sorting work table provided with a mechanism for making it move. According to this sorting work table 1, the worker is arranged in a straight line along a conventional linear conveyor and does not perform sorting work, but surrounds the donut disk-shaped turntable 4. Thus, it becomes possible to perform sorting work.

  The sorting work table 1 includes an outer edge side ring 2, an inner edge side ring 3, a rotating table 4, a plurality of (eight in FIG. 2) vertical rotating wheels 5, 5.

As shown in FIG. 1, the separation work table 1 having these components can be installed in an industrial waste sorting factory by assembling a portion that becomes the base 8 with a steel frame or the like. Yes.

  In order to reduce the weight as much as possible, the turntable 4 is made of carbon fiber and has a donut disk shape (a donut disk width of about 3 m), and the outer diameter of the donut disk shape (where the outer ring 2 is installed) The inner diameter of the donut disk shape (the place where the inner edge side ring 3 is installed) is about 2 m to 5 m. The turntable 4 is mounted in a state of being fixed on the outer edge side ring 2 and the inner edge side ring 3, and the height of the outermost peripheral edge and the innermost peripheral edge is about 10 cm higher than the horizontal plane. (See FIG. 2 (b)). The outer edge side ring 2 and the inner edge side ring 3 are provided with a non-slip material such as rubber on the side of the L-shaped portion in contact with the vertical rotating wheel 5 and the horizontal rotating wheel 7 in order to prevent an idle state during rotation. Alternatively, the surface may be anti-slip processed. The base 8 is formed by assembling a metal such as a steel frame from the side so that the side surface has a mesh pattern, and the shape viewed from directly above is a regular octagon. A column 6 is erected at the apex portion.

  The outer edge side ring 2 in the installed state has an L-shaped cross section (the length of the L-shaped bottom portion (vertical component at the time of installation) is about 20 cm), and has a diameter of about 5 to 8 m. It is a ring-shaped member of a steel material (such as a general structural rolled steel) having a width of about 20 cm to 30 cm. On the other hand, the inner edge side ring 3 in the installed state has an L-shaped cross section (the length of the L-shaped bottom part (vertical component at the time of installation) is about 20 cmm), and the diameter is about 2 m to 3 m. A ring-shaped member made of a steel material (such as a general structural rolled steel) having a ring width of about 15 cm to 20 cm.

  Then, the vertical rotating wheel 5 is rotatably installed in contact with the horizontal part lower side in the installed state of the outer edge side ring 2 and the horizontal part lower side in the installed state of the inner edge side ring 3 (FIG. 2B). )reference). The vertical rotating wheel 5 has a diameter of about 15 cm to 20 cm and a width of about 3 cm to 8 cm, and can rotate around the central axis 9 (the central axis 9a of the vertical rotating wheel 5) (about 5 cm to 10 cm in length). Both ends of the central shaft 9 (the central shaft 9 a of the vertical rotating wheel 5) are fixed to a support column 6 installed in the downward direction of the vertical rotating wheel 5 via a central shaft fixing member 10.

  The vertical rotating wheel 5 is installed so as to support the weight of the rotating table 4 from below. In short, a function for holding the turntable 4 horizontally so as to be rotatable is required. Therefore, the position of the uppermost part of the vertical rotating wheel 5 is flush with the position in the radial direction from the rotation center of the rotary table 4 (the center axis 9 and a line drawn in the radial direction from the rotation center of the rotary table 4). Are arranged in parallel to each other), and a plurality of them are arranged symmetrically in order to improve the balance. In addition, a part of the vertical rotating wheel 5 can be driven. That is, one of the vertical rotating wheels 5, 5,... Is the drive wheel 5a, and the other vertical rotating wheels 5, 5,. The diameters of the drive wheel 5a and the driven wheel 5b may be different, but it is necessary to install them so that the uppermost positions of the drive wheel 5a and the driven wheel 5b (vertical rotating wheels 5, 5,...) Are flush with each other. is there. The driving wheel 5 a of the vertical rotating wheel 5 is a motor as a driving device, and can be shifted and turned on and off by an operation switch provided near the turntable 4.

  And two horizontal rotating wheels 7 and 7 are installed so as to come into contact with the vertical portion of the outer edge side ring 2 from the outer peripheral direction. Each of the horizontal rotating wheels 7 and 7 has a diameter of about 15 cm to 20 cm and a width of about 3 cm to 8 cm, and can rotate around the central axis 9 (the central axis 9b of the horizontal rotating wheel 5) (length of about 5 cm to 10 cm). Both ends of the central shaft 9 (the central shaft 9b of the horizontal rotating wheel 5) are fixed downward (by a fixing means not shown). Note that the two horizontal rotating wheels 7 and 7 are installed at positions facing each other (a point-symmetric position at the center of the turntable 4) (see FIG. 2). The horizontal rotating wheel 7 has a central axis 9 (center axis 9b of the horizontal rotating wheel 5) (from the center axis 9 and the center of rotation of the rotating table 4) in the vertical direction so that the rotating table can be supported so as not to move in a horizontal plane. The lines drawn in the radiation direction are perpendicular to each other.

<Working mechanism of sorting worktable>
FIG. 3 is an explanatory view showing an installation state of the vertical rotating wheel 5 and the horizontal rotating wheel 7. Specifically, FIG. 3A shows the positional relationship of the vertical rotating wheel 5 with respect to the outer edge side of the rotating table 4 (directly below the outer edge side ring 2) (or the inner edge side (inner edge side ring of the rotating table 4). 3 (b) shows the positional relationship with respect to the outer edge side of the rotating table 4 of the horizontal rotating wheel 7 (the outer periphery of the outer ring 2) (or the horizontal rotating wheel). 7 shows a positional relationship with respect to the inner edge side of the rotary table 4 (the outer periphery of the inner edge side ring 3).

  A vertical rotating wheel 5 installed on the outside of the turntable 4 (directly below the outer ring 2) is installed at the upper end of the column 6, and is rotatable while contacting the lower side of the horizontal part of the outer ring 2. (See FIG. 3A). More specifically, the central axis 9 of the vertical rotating wheel 5 (the central axis 9 b of the horizontal rotating wheel 5) is installed on the central axis fixing member 10, and the central axis fixing member 10 is further fixed to the column 6. On the other hand, the vertical rotating wheel 5 installed inside the turntable 4 (directly below the inner edge side ring 3) is rotatably installed in contact with the lower side of the horizontal part of the inner edge side ring 3.

  The central axis 9 of the vertical rotating wheel 5 (the central axis 9 a of the vertical rotating wheel 5) serves as the central axis fixing member 9 in the same manner as the vertical rotating wheel 5 installed on the outside of the turntable 4 (directly below the outer edge side ring 2). Further, the center shaft fixing member 9 is fixed to the support column 6. And not all the vertical rotating wheels 5 are rotated by the action of an external driving force (not shown), but some vertical rotating wheels 5 are rotated by the action of an external driving force (not shown). It has become. Some of the vertical rotating wheels 5 that can be rotated by the action of an external driving force are connected to a driving device (motor) by a chain, a timing belt, or the like, and are activated by the operation of the driving device (motor). The motor rotates at a predetermined rotation speed. When there are a plurality of vertical rotating wheels 5 that can be rotated by the action of an external driving force, the vertical rotating wheels 5 rotate in synchronization at a predetermined rotational speed. ing.

  The horizontal rotating wheel 7 is installed so as to come into contact with the vertical portion in the cross-sectional shape of the outer edge side ring 2 from the outer peripheral direction. The horizontal rotating wheels 7 are installed at positions facing each other (a point-symmetric position at the center of the turntable 4). Specifically, the central shaft 9 of the horizontal rotating wheel 7 (the central shaft 9b of the horizontal rotating wheel 5) is installed on the central shaft fixing member 10, and the central shaft fixing member 10 is fixed (fixing method). Is not shown). And it can be rotated by the action of an external driving force (not shown). All the horizontal rotating wheels 7 are rotated by the action of an external driving force (not shown), unlike the vertical rotating wheels 5. Some vertical rotating wheels 5 and horizontal rotating wheels 7 that can be rotated by the action of an external driving force are connected to a driving device (motor) by a chain, a timing belt, or the like. By the operation of the (motor), it rotates synchronously at a predetermined rotational speed.

  The operation mechanism as described above shows one embodiment (one operation mechanism) of the present invention, and the following patterns can be considered as the operation mechanism in the sorting work table 1 according to the present invention. That is, (1) some vertical rotating wheels 5 are rotated by the action of an external driving force, horizontal rotating wheels 7 are also rotated by the action of an external driving force (pattern 1), and (2) the vertical rotating wheels 5 are The horizontal rotating wheel 7 is an operating mechanism that rotates by the action of the external driving force (pattern 2), but does not rotate by the action of the external driving force.

<Effect of sorting work table>
The sorting work table 1 has a donut disk shape when viewed from directly above, and the mixed waste moves on the rotating table 4 having such a shape (that is, the shape when viewed from directly above is a donut disk shape). This is a method of moving the mixed waste on the circular turntable while the mixed waste is rotating), so that the mixed waste is not removed unless the mixed waste is removed from the turntable 4 by the sorting operation. It will come back to the same place over and over again. Therefore, even if the separation work of the mixed waste that has flown first before the worker cannot be completed for some reason, the separation work of the mixed waste will not be missed in the end.

  Because of this feature, even if all workers have to leave the place temporarily (emergency for several minutes, toilets, etc.), there is no need to stop the device and stop the work. Even if it is handled by several people, if one or two people have to leave the place, there is no need to adjust the (separation line) operation speed of the device. In addition, mixed waste to be sorted can be received from any location on the sorting work table 1 according to the convenience of layout and the like.

  The vertical rotating wheel 5 is rotatably installed in contact with the lower horizontal portion of the outer edge side ring 2 and the lower horizontal portion of the inner edge side ring 3, and at the same time, It is installed on the outside and inside the vertical part of the inner ring 3 and guards the turntable 4 from both sides, so that it is possible to minimize the displacement with respect to the column 6 due to vibration or centrifugal force during rotation. it can. In short, it acts as a turntable 4 guide so that the position of the turntable 4 does not fall off the position of the column 6. Further, the horizontal rotating wheel 7 is installed at a facing position (a point-symmetric position at the center of the rotating table 4; see FIG. 2), and rotates while holding the rotating table 4 from both sides so as not to be displaced in the horizontal direction. Therefore, the position of the turntable 4 with respect to the column 6 is fixed.

  Further, the horizontal rotating wheel 7 is installed at a plurality of locations so as to abut on the outer edge side ring 2 from the outer peripheral direction and to the inner edge side ring 3 from the inner peripheral direction, and functions as a stopper. Therefore, the rotational energy of some vertical rotating wheels 5 that can be rotated by the action of an external driving force can be efficiently transmitted to the sorting work table 1. Furthermore, the height of the outermost peripheral edge and the innermost peripheral edge of the turntable 4 is high, and the mixed waste to be separated by centrifugal force during rotation does not jump out of the turntable 4. Ingenuity has been made.

<Example of changing sorting worktable>
The sorting worktable according to the present invention is not limited as in the above-described embodiments, but includes an outer edge side ring, an inner edge side ring, a rotating table, a vertical rotating wheel, a column, a horizontal rotating wheel, a base, The configuration of the central shaft, the central shaft fixing member, and the like can be appropriately changed as necessary without departing from the spirit of the present invention.

  For example, it is possible to add a horizontal rotating wheel (which can be rotated by the action of an external driving force) to be in contact with the outer edge side and the vertical part of the inner edge side ring from the outer circumferential direction and from the inner circumferential direction. . In such a case, in the present invention, when rotating the turntable together with the horizontal rotating wheel (which can be rotated by the action of an external driving force) installed so as to contact the vertical portion of the outer edge side ring from the outer peripheral direction. Since the same level of force that presses the turntable acts from both sides of the turntable, the position of the turntable with respect to the column is fixed without shifting even if there is centrifugal force or vibration during rotation.

  In addition, the separation worktable is provided with a gear-shaped portion in the vertical portion in the cross-sectional shape of the outer edge side ring and the vertical portion in the cross-sectional shape of the inner edge side ring, and by combining a plurality of gears instead of the vertical rotating wheel and horizontal rotating wheel A mechanism that rotates the turntable may be used. Further, as a concept different from the present invention, a mechanism may be adopted in which a center drive shaft is installed at the center (of the turntable) of the sorting work table and the center shaft is rotated by an external drive force. Furthermore, the turntable may be installed inclined toward the worker side, or the turntable, the outer edge side ring, and the inner edge side ring may be integrated.

  Since the separation worktable according to the present invention has excellent effects as described above, it can be suitably used as an apparatus used for industrial waste separation work in the field of industrial waste treatment by human separation. it can.
